This invention' relates A,to ink shutoff means for rotary printingv presses and refers more particu- 'larly to a combination page and column ink adjustment comprising means for shuttingV olf vpage widths of ink'froni the fountainroller from stations positioned within the respective page widths along the roller, and means located operatively between the page shutoii and the roller for partiallyshutting off ink from column widths of the roller, the column adjustment means being controlled from a common station by Warped rods' loosely journalled soas to maintain any rotational position to which they may be set.

' Objects and advantages of the invention will be set forth inV part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, vthe same being realized and attained by means of the instrumentalities 'and combinations pointed out inthe appended claims.

The invention consists in the novel parts,con structions, arrangements, combinations and improvelnents herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one enibodiment' of the'invention, and together with the description, serve toexplain the principles ofthe invention.

'I heA present `invention has for its object the provision of a quicker and more convenient shutoff and adjusting means for the ink fountain of aprin'ting press. A further object is the provision of separately operable means for page shutolf and column adjustment. A further object is the provision .of Ya central station controlling all the column adjustments. A further object is the provision of column adjusting actuating means terminating in a central stationv and adaptedl to retain vtheir respective setting without furtherattention'from the operator. A further, object is to provide a page shutoff which on being released restores the previously existing column adjustment. O/ther objects will become apparent in the course of the following specification.

" zclaiins. (01.101-365) In accordance with'the illustrative embodiment of the u present invention there is provided a doctor blade carrier capacitated to carry a doctor blade, preferably of page width, in operative'relation to the fountain roll. The rear edge of the ldoctor blade is affixed to the carrier in conventional manner.v The carrier has a longitudinal channel into which open a plurality of*V bore holes the axes of which are slightly inclined from the vertical. Cylindrical nuts with square headsengaging the channel walls are slidable in the bores, and into each is threaded a screw, each screw being adapted to engage the doctor blade and depress same for columnar ink adjustment. The upper endsof the screws are unthreaded andslide in bores formed in a pivot bar in the 'carrierfunit Substantially coincident longitudinally withthe doctor blade is the page slluto` board, fcomprising a parti-cylindrical lip engaging a correspondingchannel extending longitudinally of thepivot bar and in the upper forward corner ofthe foarrier viewed in cross section, this channel being open downwardly and rearwardly. The page shutoff board extends rearwardly from this chana spring loaded plunger which is actuatedv by a" manually operated cam lever pivoted inthe carrier frame. Screws arethreaded into theboard and extend from the bottom surface thereof Vto engage the column adjusting screws. :The bodies of the latter carry worm gears which are engaged by suitably supported worms on the endsorods, all of the rods associated with one page extending in the same direction from their respective worms andk terminating in squared Vends supportedin and extending through a common control plate. The rods are flexible and areV maintained in a warped condition in loose bearings. V;

It is evident from the above that the pressman standing at the control plate may regulate the ink supply to each column served by the, fountain by turning the squared end of the rod connected to the respective adjusting screw, and lthat the setting of each screw will be maintained by the frictional engagement of the elements of the worm and gear and the warped rodin itsloose bearings. The loose bearings, which may be mere l drilled` plates, are desirable for their simplicity and economy. The page shutoi is accomplished by movement of the cam lever, whichv depresses the shutoli board, depressing allthe column adroller I2 and ductor roll tI3,allfih''cdljientitjnalf manner. The fountain blade I4 is supportedgin operative relationship to thefountainroller I2,

being ailixed along its rear :edge vx"to the lblade 4-jsifliaredor otherwise 'forni'ed Vto receive la tool for imparting rotary motion. The housing 53 extends laterally of the press from blade carrier l 'I5 to index plate 5I and is closed by a removable I0 supports tlieiink top'cover 54.
